Re: generic container library

[Marin David Condic <nobody@noplace.com>]

For current projects, I'm using a home-grown container library that is 
based on a class heierarchy. It implements the needed stream attributes 
and it really works rather spiffy as you build things up from the class 
heierarchy. If I build up all the data for a given app from the base 
class one single "Load" or "Store" operation and BAM! Ada takes care of 
it automagically.

I liked the article on Charles. Its good to know that you plan on adding 
the necessary stream attributes since this library seems to be gaining 
some acceptance as a de facto standard. Its also good to know that when 
it gets into the ARM that the plan there is to provide for persistance. 
Dunno why that didn't seem intuitively obvious when people started 
thinking about ADTs and container libraries, but most of them don't 
provide a means of dealing with persistance.
